KENNEDY SPACE CENTER, FL – Following the flawless blastoff of the SpaceX Falcon 9 booster and Dragon cargo ship on Tuesday, April 14, the resupply vessel arrived at the International Space Station today, April 17, and was successful snared by the outposts resident ‘Star Trek’ crewmate, Expedition 43 Flight Engineer Samantha Cristoforetti of the European Space Agency, donning her futuristic outfit from the famed TV show near and dear to space fans throughout the known galaxy!

Cristoforetti grappled the SpaceX Dragon freighter with the station’s robotic arm at 6:55 a.m. EDT, with the able assistance of fellow crewmate and Expedition 43 Commander Terry Virts of NASA.

Dragon is hauling critical supplies to the six astronauts and cosmonauts serving aboard, that now includes the first ever ‘One-Year Mission’ crew comprising NASA’s Scott Kelly and Russia’s Mikhail Kornienko.

Cristoforetti and Virts were manipulating the 57.7-foot-long (17-meter-long) Canadian-built robotic arm while working inside the stations seven windowed domed Cupola, that reminds many of Darth Vader’s lair in ‘Star Wars’ lore.

The SpaceX Dragon blasted off atop a Falcon 9 booster from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida on April 14, 2015 at 4:10 p.m. EDT (2010:41 GMT) on the CRS-6 (Commercial Resupply Services-6) mission bound for the space station.

The Dragon cargo spacecraft was berthed to the Earth facing port of Harmony module of the International Space Station at 9:29 a.m. EDT.

The entire multihour grappling and berthing operations were carried live on NASA TV, for much of the morning and everything went smoothly.

Overall CRS-6 is the sixth SpaceX commercial resupply services mission and the seventh trip by a Dragon spacecraft to the station since 2012.

Dragon is loaded with more than 4,300 pounds of supplies, science experiments, and technology demonstrations, including critical materials to support about 40 of more than 250 science and research investigations during the station’s Expeditions 43 and 44.

Among the research investigations are a fresh batch of 20 rodents for the Rodent Research Habitat, and experiments on osteoporosis to counteract bone deterioration in microgravity, astronaut vision loss, protein crystal growth, and synthetic muscle for prosthetics and robotics.

An Espresso machine is also aboard to enhance station morale during the daily grind some 250 miles above Earth.

Following the April 14 launch, SpaceX made a nearly successful soft landing of the first stage on an ocean floating platform in the Atlantic Ocean. Read my story – here.

SpaceX Resets CRS-6 Space Station Launch to April 13 with Booster Landing Attempt

The clock is ticking towards the next launch of a SpaceX cargo vessel to the International Space Station (ISS) hauling critical supplies to the six astronauts and cosmonauts serving aboard, that now includes the first ever ‘One-Year Mission’ station crew comprising NASA’s Scott Kelly and Russia’s Mikhail Kornienko.

The mission, dubbed SpaceX CRS-6 (Commercial Resupply Services-6) will also feature the next daring attempt by SpaceX to recover the Falcon 9 booster rocket through a precision guided soft landing onto an ocean-going barge.

SpaceX and NASA are now targeting blastoff of the Falcon 9 rocket and Dragon spacecraft for Monday, April 13, just over a week from now, at approximately 4:33 p.m. EDT from Space Launch Complex 40 at Cape Canaveral Air Force Station in Florida.

NASA Television plans live launch coverage starting at 3:30 p.m.

The launch window is instantaneous, meaning that the rocket must liftoff at the precisely appointed time. Any delays due to weather or technical factors will force a scrub.

The backup launch day in case of a 24 hour scrub is Tuesday, April 14, at approximately 4:10 p.m.

Falcon 9 launches have been delayed due to issues with the rockets helium pressurization bottles that required investigation.

The Falcon 9 first stage is outfitted with four landing legs and grid fins to enable the landing attempt, which is a secondary objective of SpaceX. Cargo delivery to the station is the overriding primary objective and the entire reason for the mission.

An on time launch on April 13 will result in the Dragon spacecraft rendezvousing with the Earth orbiting outpost Wednesday, April 15 after a two day orbital chase.

After SpaceX engineers on the ground maneuver the Dragon close enough to the station, European Space Agency (ESA) astronaut Samantha Cristoforetti will use the station’s 57.7-foot-long (17-meter-long) robotic arm to reach out and capture Dragon at approximately 7:14 a.m. EDT on April 15.

Cristoforetti will be assisted by fellow Expedition 43 crew member and NASA astronaut Terry Virts, as they work inside the stations seven windowed domed cupola to berth Dragon at the Earth-facing port of the Harmony module.

Overall CRS-6 is the sixth SpaceX commercial resupply services mission and the seventh trip by a Dragon spacecraft to the station since 2012.

CRS-6 marks the company’s sixth operational resupply mission to the ISS under a $1.6 Billion contract with NASA to deliver 20,000 kg (44,000 pounds) of cargo to the station during a dozen Dragon cargo spacecraft flights through 2016 under NASA’s original Commercial Resupply Services (CRS) contract.

Dragon is packed with more than 4,300 pounds (1915 kilograms) of scientific experiments, technology demonstrations, crew supplies, spare parts, food, water, clothing and assorted research gear for the six person Expedition 43 and 44 crews serving aboard the ISS.

The ship will remain berthed at the ISS for about five weeks.

The ISS cannot function without regular deliveries of fresh cargo by station partners from Earth.

The prior resupply mission, CRS-5, concluded in February with a successful Pacific Ocean splashdown and capsule recovery.

The CRS-5 mission also featured SpaceX’s history making attempt at recovering the Falcon 9 first stage as a first of its kind experiment to accomplish a pinpoint soft landing of a rocket onto a tiny platform in the middle of a vast ocean using a rocket assisted descent.

As I wrote earlier at Universe Today, despite making a ‘hard landing’ on the vessel dubbed the ‘autonomous spaceport drone ship,’ the 14 story tall Falcon 9 first stage did make it to the drone ship, positioned some 200 miles offshore of the Florida-Carolina coast, northeast of the launch site in the Atlantic Ocean. The rocket broke into pieces upon hitting the barge.

Listen to my live radio interview with BBC 5LIVE conducted in January 2015, discussing SpaceX’s first attempt to land and return their Falcon-9 booster.

Watch for Ken’s onsite coverage of the CRS-6 launch from the Kennedy Space Center and Cape Canaveral Air Force Station.

Can A Mega-Magnetic Field Protect Astronauts From Radiation?

A bunch of people really, really want to go to the Red Planet on the proposed one-way Mars One trip; more than 1,000 applicants are being considered in Round 2 selections. They will face, however, more radiation during their journey that could put them at higher risk of cancers down the road. While the solution could be to add more shielding to a spacecraft, that’s both heavy and expensive.

Enter the alternative: a magnetic field. A group calling itself the EU Project Space Radiation Superconductive Shield says their technology will “solve the issue of radiation protection in three years” and is seeking academic collaborations to make that happen. Here’s how it will work:

“The SR2S superconducting shield will provide an intense magnetic field, 3,000 times stronger than the Earth’s magnetic field and will be confined around the space craft,” a press release states.

“The magnetic fields will extend to about 10 metres in diameter and ionizing particles will be deflected away. Only the most energetic particles will penetrate the superconducting shield, but these will contribute the least to the absorbed radiation dose as their flux is negligible. This will address the issue of suitability of people for space travel as it will open up eligibility for space travel regardless of gender.”

That last bit refers to some radiation guidelines highlighted a few months ago. Peggy Whitson, a veteran NASA astronaut, said publicly that women fly far fewer hours in space than men. That’s because space authorities apply lower “lifetime” radiation limits to females (for biological reasons, which you can read more about here).

The project team includes participation from the Italian National Institute of Nuclear Physics, General Company For Space (CGS SpA), Columbus Superconductor SpA, Thales Alenia Space – Italia S.p.A., the French Commission of Atomic Energy and Alternative Energies, and the European Organization for Nuclear Research (CERN).

“We have already made significant progress since the beginning of the project and believe we will succeed in this goal of solving the radiation protection issue,” stated Roberto Battiston, who leads the project and is also a professor of experimental physics at the University of Trento in Italy. The project started a year ago.

“In the last few months, the international teams working at CERN have solved two major technical issues relevant to the superconducting magnets in space (i) how to make very long high temperature superconducting cables join together in a shorter segment without losing the superconducting properties and (ii) how to ensure protection of long high temperature cables from a quench.”
