Memorable Space Tweeps of 2012

To space Tweeps, Twitter is so much more than just a news service. It’s a community, a spot where everyone can showcase their interests and form professional bonds with each other.

The most prominent space-themed Twitter accounts of 2012 somehow transcended their original purpose, too. A NASA Mars Curiosity account ended up hobnobbing with comedian Steve Martin, and a space-station-passing service suddenly found itself in bit of a Twitter controversy.

Here are 10 of some of the most memorable Twitter accounts from this year. Yes, there’s a lot of Mars reflected here, but the entities quoted below explore all over the Universe.

@astro_andre

Dutch astronaut André Kuipers spent the first half of 2012 orbiting Earth. From his perch aboard the International Space Station, he participated in the historic SpaceX docking in May and finished 50 experiments. But rather than dwell on these achievements, he spent his tweeting time in space showing his gorgeous pictures of Earth. Maybe that old Apollo phrase about going to space and discovering Earth still has resonance today.

@BadAstronomer

Phil Plait is a good scientist-cum-journalist to follow in general, because his tweets constantly show his love of the universe. (“Embiggen!” he would perhaps shout at this point.) What made him stand out in 2012, though, was his willingness to use his immense Internet fame to showcase the work of others, such as his frequent Tweeting and posting of great space images and timelapse videos, or helping to ‘kickstart’ new projects and help them get off the ground, such as the Uwingu astronomy startup. He shows that Twitter most definitely has altruistic use.

@chrislintott

Chris Lintott demonstrated how to handle a situation when a close, beloved colleague passes away. The co-presenter of The Sky At Night was among the first official voices giving word of Sir Patrick Moore‘s death, and he retweeted messages of remembrance from colleagues and ordinary people. Nicely done, during what was a difficult time.

@claratma

Hard to believe Clara Ma is a mere 15 years old when reading tweets like this. The Kansas-based teenager named the Mars Curiosity rover. This year, she has been graciously fielding interview requests from journalists, and messages of support from NASA employees, ever since the rover made it to Mars in August.

@Cmdr_Hadfield

OK, I’ll admit my bias here: I’m Canadian. I’ve been watching Canadian astronaut Chris Hadfield since he was selected 20 years ago. But in the Twittersphere, he’s made an impact. My fellow journalists publicly speak about his work, with respect. His tweets showing his astronaut training are favourited and retweeted by people all over the world. And as the first Canadian to command the International Space Station next year, Hadfield will be a force to watch in 2013.

@MarsCuriosity

Three NASA employees are behind the “hive mind” of @MarsCuriosity. The official feed for the Curiosity mission skyrocketed to fame in 2012, receiving tweets from celebrities ranging from Britney Spears to the aforementioned Steve Martin. In this case, happily, “official” doesn’t always mean “staid.” The Twitter account has been a bevy of jokes and cheerful updates in between the standard scientific results.

@NASAVoyager

At 35 years and counting, the two NASA Voyager spacecraft have ventured into the newer field of social media. The accounts received more attention as Voyager 1 reached the edge of our solar system in 2012. It’s hard to summarize solar and interstellar physics in just 140 characters, but this official NASA account does it quite well.

@SarcasticRover

Nothing says pop culture as seeing your catchphrase — “Let’s Do a Science!” — repeated ad nauseum by planetary scientists on Twitter. The brainchild of Jason Filiatrault, this account is a parody of the official Mars Curiosity Twitter and depicts a rover angrily making its way around Mars after being ordered there by unfeeling humans. Besides wry observations of Martian life, the rover broadcasts its point of view on recent discoveries in a unique way.

@SpaceX

Not often that a corporate account uses four exclamation marks in a row, but the space geeks would argue this is justified. SpaceX made headlines and history in 2012 when the Dragon spacecraft berthed with the International Space Station — a first for a private spacecraft. SpaceX’s Twitter not only broadcasts mission news, but also seeks out mentions of the company and adds commentary.

@twisst

Just before the International Space Station passes by overhead, @twisst gives you a heads-up that you’ll be able to see it. This popular account’s service was briefly shut down in 2012 due to Twitter’s concerns about the duplicate accounts required to make the service work. But a few tweaks later, @twisst returned — to the delight of its thousands of followers.

Soyuz Docks to Space Station with New Crew and 32 Fish

Three new crew members — and 32 fish — are now at the International Space Station. Kevin Ford, Oleg Novitskiy and Evgeny Tarelkin joined their Expedition 33 crewmates after docking the Soyuz TMA-06M spacecraft to the Poisk module at 12:29 UTC (8:29 a.m. EDT) Thursday. They join Commander Suni Williams and Flight Engineers Aki Hoshide and Yuri Malenchenko who have been on board since July 17. Hatches between the International Space Station and the Soyuz will open later today after pressure and leak checks.


32 Asian medaka fish were also launched along with the crew on Tuesday from the from the Baikonur Cosmodrome, Kazakhstan. No word yet if all the fish survived the launch, but they will be placed in a new aquarium in the Japanese Kibo lab module for research on how the fish react to microgravity and space radiation. It should also be fun for the astronauts — and the public — to watch the fish swim about in the Aquatic Habitat.

The Aquatic Habitat, or AQH, is a Japanese Space Agency, or JAXA, facility that will enable the study of fish aboard the International Space Station. (JAXA)

Progress Resupply Ship Takes Fast-Track to ISS, Arriving 6 Hours After Launch

After a flawless launch, an unmanned Russian Progress resupply ship used a new expedited technique to reach the International Space Station in hours instead of days. Progress 48 was loaded with almost three tons of food, fuel and supplies for the six crew members, and it docked successfully to the Pirs docking compartment on August 1, just six hours after the launch from the Baikonur Cosmodrome in Kazakhstan at 19:35 UTC (3:35 p.m. EDT, 1:35 a.m. Aug. 2 Baikonur time). The fast trip and rendezvous was designed to test a method for conducting additional firings of the Progress engines early in its mission to expedite the time required for a Russian vehicle to reach the complex.

Russian officials say the technique could be applied to manned Soyuz vehicles in the future to improve crew comfort and extend the life of the Soyuz return vehicle.

Russian cosmonaut Gennady Padalka has been quoted as saying it is every cosmonaut’s dream to only have a 6-hour flight in the cramped Soyuz!

Russian engineers and managers are still assessing the new technique, but by all appearances the quick trip seemed to be a great success. This Progress vehicle will stay at the ISS until December.

During the docking, NASA also tested a new technique of attitude control for the ISS which will save fuel, requiring 10 times less fuel to put the station in the proper orientation relative to Earth for the unpiloted cargo vehicle’s arrival.

According to Pooja Jesrani, lead attitude determination and control officer (ADCO) for this expedition at the Mission Control Center in Houston, the new maneuver is called the optimal propellant maneuver, or OPM. OPM is an improvement on the standard zero propellant maneuver, or ZPM, also developed by Draper Laboratory. The OPM takes into account the need to make the orientation, or attitude, changes to the space station faster than the ZPM. This speed avoids thermal concerns on the exterior of the station’s modules.

“Maneuvers such as the OPM will increase the International Space Station’s efficiency by using less propellant,” Jesrani said. “Additionally, the reduction in thruster firings during an OPM results in the station enduring lower structural loads. These benefits, among others, will help increase the longevity of the station.”

The maneuvers to and from the docking attitude are expected to save more than 90 percent of the fuel typically used when a Russian cargo spacecraft docks with the orbiting outpost.

Current Astronauts in Orbit Exchange Notes with John Glenn

If you weren’t able to watch live, this is a fun exchange between the current astronauts in orbit, talking with one of the first people ever to see Earth from an orbital perspective. The astronauts aboard the International Space Station talked with Senator John Glenn during an in-flight call this week, to celebrate the 50th anniversary of Glenn’s historic Friendship 7 space flight. The event was part of NASA’s Future Forum at The Ohio State University in Columbus, Ohio.

A Beginner’s Guide to Photographing The International Space Station (ISS)

Long Exposure Photograph of the ISS Credit: Mark Humpage

[/caption]
If you have seen the International Space Station (ISS) pass over a few times with your own eyes, (here’s our guide on seeing it) you may want to have a go at photographing it.

Photographing the ISS is very worthwhile and gratifying. There are two basic methods; one being easy and the other being a little more difficult. Both methods are incredibly rewarding and good results can be obtained fairly quickly, once you have mastered the basics.

Method 1:

Discovery and ISS pass over the UK on March 7, 2011, captured by Will Gater.

You will need a DSLR camera or another type of camera which is capable taking long exposures. Incredibly important is having a tripod or somewhere you can place your camera without it getting vibrations or movement.

Find out when and where the ISS will be passing over your location and choose a part of the sky the ISS is passing through at which you can point your camera.

Experiment with your camera settings, to get colours and exposures correct beforehand and do a couple of long exposure test shots of anything from 15 to 60 seconds. You can do shorter or longer exposures but this is up to you, depending your equipment and how artistic you want to be.

This method will produce a long white streak or line, which will show the path taken of the International Space Station as it passes over. This is the most common method for amateurs.

Method 2:

You will need a telescope, a webcam, and a strong mount or tripod. Set up your telescope and mount, along with webcam with a laptop and make sure of the time and where the ISS will be passing over your location.

In this method we will use the telescope to magnify and see the ISS up close while recording a movie (AVI). We will then stack the frames of the recorded movie in a specialist image enhancing program such as Registax.

Insert your WebCam into the telescope focusing tube using an adapter (available from astronomy stores) and connect the cables to your laptop. When the ISS is due, start recording and track the space station using a finder scope or computerized mount.

The difficult part of this method is tracking the ISS and keeping it in the field of view of the telescope while recording the video file. It is recommended that you set your mount in “Alt/ Az” mode or use a Dobsonian telescope so that you have free movement of telescopes optical tube assembly. You will basically be using the telescope as a giant video camera and you need to keep the ISS in shot for as long as possible.

This method is very difficult as the ISS has been magnified highly while moving very quickly and can be easily lost out of the field of view, or there can be too much movement (shaking) in the video. This method requires much practice.

Once you have been able to get a video of the ISS passing over, you can feed your video file into software such as RegiStax and the program will sort each individual frame, removing bad frames and stacking good frames to create a very clear image.

This method is fantastic for creating close up images with detail on the International Space Station; you can also see docked spacecraft. You can also use this method for trying to image other Earth-orbiting satellites, too.

Beginner’s Guide to Seeing the International Space Station (ISS)

Most readers of Universe Today are familiar with the International Space Station or “ISS” as it’s often referred to. But just in case you are visiting our site for the first time, the ISS is a huge space station orbiting Earth that serves as an orbital laboratory, factory, testing ground and home; crew members conduct experiments from biology to astronomy, including experiments for prolonged exposure to life in space for future missions to the Moon and beyond.

The ISS is major accomplishment for NASA (US), ESA (Europe), JAXA (Japan) CSA (Canada) and all the countries involved (16 in all). The space station is just over 72 m long by 108 m wide and 20 m high; it is maintained at an orbital altitude of between 330 km (205 mi) and 410 km (255 mi) and travels at an average speed of 27,724 kilometres (17,227 mi) per hour, completing 15.7 orbits per day.

One of the best things about the ISS is that you can see it with your own eyes from Earth! It’s very easy to watch the International Space Station pass over your own backyard!

All you need to do is understand when the ISS is going to be passing over your location and where to look for it in the sky. You can check this by using an ISS pass predictor app or website such as Heavens-Above.

Once you have found out when the ISS will pass over your location, all you need to do a few minutes before the pass is go outside and start looking in the right direction of the sky.

The International Space Station always passes over starting from a westerly part of the sky, but not always from the same point. It can be low on the horizon for some passes and very high others. Most of the apps or websites will tell you what direction in the sky the pass will start and end and how many degrees above the horizon the starting and ending points are. Also included are the highest altitude the ISS will be. For example, if the maximum elevation is listed as somewhere between 74-90 degrees above the horizon, the ISS will be passing almost straight overhead (Just like you learned in geometry, 90 degrees would be straight up). If you aren’t sure about where to look, a good rule of thumb is that your fist outstretched at arm’s length is 10 degrees. If the ISS will be first be seen 40 degrees above the horizon, look four fist-lengths above the horizon. Check apps and websites for where and what track the ISS will take on each individual pass.

When the station passes over it will travel from a westerly direction, heading in an easterly direction. An average good pass can last about 5 minutes.

The ISS looks like an incredibly bright, fast-moving star and can be mistaken for an aircraft. However, the ISS has no flashing lights and it can be much brighter. It seemingly just glides across the sky.

Short passes can last a few seconds to a few minutes and you can see the international space station slowly move into the Earth’s shadow, good bright passes will show the ISS moving across the sky from horizon to horizon.

The International Space Station usually takes around 90 minutes to orbit our planet, so if you’re really lucky you can get two, or maybe even three or four passes in an evening or morning.

Not only can you see the ISS in the evening but you can also see it in the mornings as both the ISS and Sun are in the ideal position to illuminate the spacecraft at this time. The light we see from the ISS is reflected sunlight.

You can’t watch the ISS pass over during the middle of the day because in the daytime the sky is too bright (although some people with specialized equipment have seen it) and you cannot see the space station in the middle of the night, as it is in the Earth’s shadow and no light is being reflected from it.

The position that the ISS will be in the sky changes every night. The space station does not take the same track or orbital path for each orbit and this change provides good visible passes roughly every 6 weeks in each location on Earth.

Occasionally if a spacecraft such as a Soyuz crew capsule or a Progress resupply vehicle has been sent to the ISS, you will see objects preceding or trailing the station as it moves across the sky. These can either be very close to the station or the distance between the objects can be measured in minutes. To check if there are any other spacecraft with the international space station during a pass, use the pass prediction app, or the Heaven’s Above Site.

Seeing the ISS is an incredible sight! Just remember there are people on board that fast moving point of light!

Good luck!

China completes 2nd Docking to Space Lab and sets Path to Manned flights in 2012

Photo taken on Nov. 14, 2011 shows the image of Shenzhou-8 spacecraft on the electronic screen in the Beijing Aerospace Flight Control Center, in Beijing, China. The image was shot by a video camera on Tiangong-1 just after Shenzhou-8's separation from Tiangong-1.

Chinese space prowess took another major leap forward today (Nov. 14) when the unmanned Shenzhou-8 capsule successfully re-docked with China’s Tiangong-1 space lab while speeding through space and orbiting some 343 km above Earth. Today’s events pave the way for China to rapidly ramp up their human space program and loft up to two manned flights to the space lab module in 2012.

The re-docking marked only the 2nd time that China had accomplished a successful space docking, a critical technical milestone that opens the door to China’s real ambition of assembling a 100 ton operational Space Station in low Earth orbit by 2020 – about the time when the ISS might be decommissioned.

China made space history on Nov. 3 by becoming only the 3rd country on Earth – after the US and the Russia – to accomplish a space link up when Shenzhou- 8 and Tiangong-1 rendezvoused and docked in earth orbit.

Shenzhou-8 was launched to orbit on Nov. 1 atop a Long March 2F booster rocket from the Jiuquan Satellite Launch Center in the Gobi Desert in northwest China. The two Chinese built spacecraft have been joined together for 12 days.

China’s space re-docking exercise today came just hours after Russia successfully launched their Soyuz capsule with two Russians and one American bound for the ISS.

Today’s goal was to give Chinese engineers more practice and confidence in mastering the complex maneuvers required for rendezvous and docking two vehicles in space. It was carried out in daylight conditions as opposed to the nighttime conditions for the initial docking to expand the testing envelope under different scenarios.

Shenzhou-8 first disengaged from the prototype space station at about 6:37 a.m. EST and then withdrew to a distance of about 140 meters (460 ft). About 30 minutes later, mission controllers at the Beijing Aerospace Control Center monitored Shenzhou-8 as it automatically approached Tiangong-1 and completed the second docking – or “Space Kiss” as the Chinese media fondly say – at about 6:53 a.m. EST.

The combined Shenzhou-8/Tiangong-1 orbiting complex is some 20 meter in length and weighs about 16 tons. Each vehicle weighs some 8 tons. Tiangong-1 is 10.4 m in length and 3.3. m in diameter. Shenzhou-8 is 9.2 m in length

Shenzhou is China’s manned space capsule but flew this flight with no humans aboard because Chinese space officials felt it was safer and prudent and did not want to expose astronauts to excessive risk during the unprecedented docking attempts.

Following today’s complete success, the China Manned Space Engineering (CMSE) Project is pushing ahead with plans to launch up to two manned missions to Tiangong-1 in 2012 – namely Shenzhou-9 and Shenzhou-10 which are already under construction.

Both 2012 missions would be short duration flights of a few days or weeks since the Tiangong-1 module is a prototype space station module and not outfitted for long duration flights.

CMSE is evaluating a pool of Chinese astronauts already in training – including two women – for the two flights. Both women candidates are married and about 30 years of age but have not been publically identified.

It seems highly likely that one of the Shenzhou missions will include the first female Chinese astronaut.

So far China has launched six astronauts on three manned Shenzhou capsules between 2003 and 2008.

The docking mechanism on Shenzhou-8 was developed and manufactured in China, says Wu Ping, spokeswoman for the CMSE.

In two days, Shenzhou-8 is due to undock from Tiangong-1 for the final time and initiate the fiery re-entry to Earth on Nov. 17. The descent capsule will land by parachute.

These historic feats prove that China’s manufacturing and technological capabilities are surging forward and rapidly matching the Western powers and Japan in a broad swath of scientific and technical fields.

Since the forced retirement of NASA’s functioning space shuttle orbiters, only China and Russia can launch people into space.

Success ! Launch Video of Crucial Russian Rocket to ISS puts Human Flights back on Track

Photos and rocket rollout video below

The very future of the International Space Station was on the line this morning as the Russian Progress 45 cargo ship successfully launched this morning from the Baikonur Cosmodrome in Kazakhstan at 6:11 a.m. EDT (4:11 p.m. Baikonur time) on Oct. 30, 2011, bound for the ISS.

Today’s (Oct. 30) blastoff of the Soyuz rocket booster that is used for both the Progress cargo resupply missions and the Soyuz manned capsules was the first since the failure of the third stage of the prior Progress 44 mission on August 24 which crashed in Siberia.

[/caption]
The third stage is nearly identical for both the manned and unmanned versions of the normally highly reliable Soyuz booster rocket.

Today’s success therefore opens up the door to resumption of crewed flights to the ISS, which were grounded by Russia after the unexpected loss of the Progress 44 mission.

If this Progress flight had failed, the ISS would have had to be left in an uncrewed state for the first time since continuous manned occupation began more than 10 years ago and would have significantly increased the risk for survival of the ISS in the event of a major malfunction and no human presence on board to take swift corrective action.

NASA issued the following statement from Bill Gerstenmaier, associate administrator for Human Exploration and Operations at NASA Headquarters in Washington, about the launch of the Progress 45 spacecraft.

“We congratulate our Russian colleagues on Sunday’s successful launch of ISS Progress 45, and the spacecraft is on its way to the International Space Station. Pending the outcome of a series of flight readiness meetings in the coming weeks, this successful flight sets the stage for the next Soyuz launch, planned for mid-November. The December Soyuz mission will restore the space station crew size to six and continue normal crew rotations.”

Progress 45 is carrying nearly 3 tons of supplies to the ISS, including food, water, clothing, spare parts, fuel, oxygen and science experiments for use by the resident crews.

The resupply vehicle achieved the desired preliminary orbit after the eight and one half minute climb to space and deployed its solar arrays and communications antennae’s.

After a two day chase, Progress 45 will automatically link up with the ISS at the Pirs Docking Compartment on Nov. 2 at 7:40 a.m (EDT) and deliver 1,653 pounds of propellant, 110 pounds of oxygen and air, 926 pounds of water and 3,108 pounds of spare parts, experiment hardware and other supplies for the Expedition 29 crew.

The successful launch sets the stage for the launch of the station’s next three residents on Nov. 13. NASA’s Dan Burbank and Russia’s Anton Shkaplerov and Anatoly Ivanishin will arrive at the station Nov. 16, joining NASA’s Mike Fossum, Russia’s Sergei Volkov and Japan’s Satoshi Furukawa for about six days before Fossum, Volkov and Furukawa return home.

Liftoff of Burbank’s crew was delayad from the original date on September 22 following the Progress failure in August. Because of the delayed Soyuz crew launch, the handover period from one crew to the next had to be cut short.

Since the forced retirement of the Space Shuttle, the US has absolutely no way to send human crews to orbit for several years to come at a minimum and is totally reliant on Russia.

The survival of the ISS with humans crews on board is therefore totally dependent on a fully functioning and reliable Soyuz rocket.

Last Towback of a Flight Worthy Space Shuttle – Atlantis Post Touchdown Photo Album

Remember when there was a Space Shuttle. Atlantis flew the final flight of NASA’s Space Shuttle Era on the STS-135 mission and was the last flight worthy orbiter to be towed back from the Shuttle Landing Facility. Atlantis touched down on July 21, 2011 at the Kennedy Space Center. Credit: Ken Kremer

[/caption]

Space Shuttle Atlantis closed out NASA’s Space Shuttle Era with a safe touchdown on July 21, 2011 at the Kennedy Space Center in Florida at the conclusion of the STS-135 mission, the 135th and final shuttle mission.

I was extremely fortunate to be an eyewitness to history and one of the lucky few journalists permitted by NASA to follow along as Atlantis took her historic final journey back from wheels stop at Runway 15 at the Shuttle Landing Facility as a flight worthy orbiter.

A convoy of 25 specialized vehicles safe each orbiter after landing. Some four hours later, Atlantis was towed off the runway with a diesel powered tractor for about 2 miles along the tow way leading to the Orbiter Processing Facility which lies adjacent to the Vehicle Assembly Building (VAB) at KSC.

The STS-135 crew consisted of Shuttle Commander Chris Ferguson, Pilot Doug Hurley and Mission Specialists Sandra Magnus and Rex Walheim.
