The CHEOPS spacecraft is taking the first tentative steps in its mission. Back on January 29th, the spacecraft opened the cover on its lens. Now, we have the first images from CHEOPS.Continue reading “Here are the First Pictures from CHEOPS”
A trio of space travelers returned to Earth this morning from the International Space Station, including NASA astronaut Christina Koch, who set a record for the longest single spaceflight by a woman, at 326 straight days. Also coming home was ESA astronaut Luca Parmitano, who has now spent a total of 367 days in space (in two missions), more days than any ESA astronaut in history.
The crew of Expedition 61 also included Russian cosmonaut and Soyuz Commander Alexander Skvortsov, who completed his third mission for a total of 546 days in space, placing him 15th on the all-time time-in-space list.Continue reading “Record-Setting Space Travelers Return to Earth”
NASA’s Spitzer Space Telescope has reached the end of its life. Its mission was to study objects in the infrared, and it excelled at that since it was launched in 2003. But every mission has an end, and on January 30th 2020, Spitzer shut down.Continue reading “Good-bye Spitzer. We’ll Miss You But We Won’t Forget You.”
The CHEOPS (CHaracterising ExOPlanets Satellite) spacecraft just opened the cover on its telescope. The spacecraft was launched on December 18th 2019 and has so far performed flawlessly. In one or two weeks we could get our first images from the instrument.Continue reading “CHEOPS Just Opened Its Eyes to Start Studying Known Exoplanets, We Should See the First Picture in a Few Weeks”
NASA’s OSIRIS-REx arrived at asteroid Bennu in December 2018. During the past year, it’s been imaging the surface of the asteroid extensively, looking for a spot to take a sample from. Though the spacecraft has multiple science objectives, and a suite of instruments to meet them, the sample return is the key objective.
Now, NASA has narrowed the choice down to four potential sampling locations on the surface of the asteroid.Continue reading “It’s Time to Decide. Where Should OSIRIS-REx Take a Sample from Bennu?”
Japan’s Hayabusa 2 spacecraft is on its way home. The asteroid-visiting, sample-return mission departed asteroid Ryugu (162173 Ryugu) on Wednesday, beginning its year-long journey back to Earth. And it’s carrying some precious cargo.Continue reading “It’s Time for Hayabusa-2 to Come Home”
It’s time to update the rules. That’s the conclusion of a panel that examined NASA’s rules for planetary protection. It was smart, at the dawn of the space age, to think about how we might inadvertently pollute other worlds with Earthly microbes as we explore the Solar System. But now that we know a lot more than we did back then, the rules don’t fit.Continue reading “A NASA Panel Says We Don’t Need to be so Careful About Infecting Other Worlds”
The mole is still stuck.
The mole is the name given to the Heat Flow and Physical Properties Package (HP3) instrument on NASA’s Mars InSight lander. It’s job is to penetrate into the Martian surface to a depth of 5 meters (16 ft) to measure how heat flows from the planet’s interior to the surface. It’s part of InSight’s mission to understand the interior structure of Mars, and how it formed.
But it’s stuck at about 35 centimers (14 inches.) The mole can do science shy of its maximum depth of 5 meters, but not this shallow. And NASA, and the DLR (German Aerospace Center) who provided the mole, have a new plan to fix it.Continue reading “Here’s NASA’s New Plan to Get InSight’s Temperature Probe Into Mars”
Is there a more complicated and sophisticated technological engineering project than a spacecraft? Maybe a particle accelerator or a fusion power project. But other than those two, the answer is probably no.
Spacecraft like the ESA’s JUICE don’t just pop out of the lab ready to go. Each spacecraft like JUICE is a singular design, and they require years—or even a decade or more—of work before they ever see a launch pad. With a scheduled launch date of 2022, JUICE is in the middle of all that work. Now its cameras are capturing images of Jupiter and its icy moons as part of its navigation calibration and fine-tuning.Continue reading “Even Though it Hasn’t Launched Yet, JUICE Took its First Images of Jupiter and its Moons”
When SpaceIL’s Beresheet lander crashed into the Moon, it was a bitter-sweet moment for Israel’s space exploration aspirations. The privately-built spacecraft was punching above its weight class by proceeding on its journey to the Moon. Unfortunately, it crashed, ending the dream.
But Beresheet carried some unusual passengers, as part of an unusual, yet visionary, sub-mission: tardigrades.Continue reading “Hardy Tardigrades on Board Israel’s Beresheet Lander Probably Survived the Crash”
