Three things NASA learned from Mars InSight
NASA's InSight spacecraft touched down Nov. 26, 2018, on Mars to study the planet's deep interior. A little more than one Martian year later, the stationary lander has detected more than 480 quakes and collected the most comprehensive weather data of any surface mission sent to Mars. InSight's probe, which has struggled to dig underground to take the planet's temperature, has made progress, too.
There was a time when the surfaces of Mars and Earth were very similar. Both were warm, wet, and shrouded in thick atmospheres. But 3 or 4 billion years ago, these two worlds took different paths. The mission of InSight (short for Interior Exploration using Seismic Investigations, Geodesy and Heat Transport) has been to help scientists to compare Earth to its rusty sibling. Studying what the depths of Mars is made of, how that material is layered, and how quickly heat seeps out of it could help scientists better understand how a planet's starting materials make it more or less likely to support life.

NASA moves forward with campaign to return Mars samples to Earth
NASA and ESA (European Space Agency) are moving to the next phase in a campaign to deepen understanding of whether life ever existed on Mars and, in turn, better understand the origins of life on Earth.
NASA has approved the Mars Sample Return (MSR) multi-mission effort to advance to Phase A, preparing to bring the first pristine samples from Mars back to Earth. During this phase, the program will mature critical technologies and make critical design decisions, as well as assess industry partnerships.
The first endeavor of this campaign is in progress. NASA's Mars 2020 Perseverance rover launched in July and is set to land on the Red Planet Feb. 18, 2021. The car-size rover will search for signs of ancient microbial life. Using a coring drill at the end of its robotic arm, Perseverance has the capability to gather samples of Martian rock and regolith (broken rock and dust), and hermetically seal them in collection tubes.
Russia launches UK telecom satellites into space
A Soyuz rocket blasted off from the Vostochny cosmodrome in Russia's Far East on Friday carrying 36 UK telecommunications and internet satellites, the Roscosmos space agency said.
The launch was the first and only one to take place from the cosmodrome this year, Roscosmos told AFP.
The rocket took off at 1226 GMT, Roscosmos said, carrying satellites made by the British-based company OneWeb.
Originally planned for April, the launch was delayed after OneWeb collapsed and was forced to declare bankruptcy.
Last month, the UK government and Indian telecommunications giant Bharti took control of the company, investing $500 million a piece.
The London-headquartered company is working to complete the construction of a constellation of low earth orbit satellites providing enhanced broadband and other services to countries around the world.
OneWeb's first six satellites were launched by a Russian-made Soyuz rocket from the space centre in Kourou in French Guiana in February 2019.
The company launched 34 more in February this year from the Baikanour launch site in Kazakhstan, then another 34 in March.
OneWeb plans for its global commercial internet service to be operational by 2022, supported by some 650 satellites.
"Today's launch will be the first fully commercial spacecraft launch from the Vostochny cosmodrome," Roscosmos said.

ESA partnering on UK’s new space thruster test site
Today marks the start of final assembly of the UK’s new National Space Propulsion Facility. ESA is providing technical oversight and financial backing for the facility, which is being equipped with state-of-the-art infrastructure to test the most powerful engines used to shift the orbits of space missions.
