As new probes reach Mars, here's what we know so far from trips to the red planet
Tuesday, 09 February 2021 14:27
Three new spacecraft are due to arrive at Mars this month, ending their seven-month journey through space.
The first, the United Arab Emirates' Hope Probe, should have made it to the red planet this week. It will stay in orbit and study its atmosphere for one complete Martian year (687 Earth days).
China's Taiwen-1 mission also enters orbit this month and will begin scouting the potential landing site for its Mars rover, due to be deployed in May.
If successful, China will become the second country to land a rover on Mars.
These two missions will join six orbiting spacecraft actively studying the red planet from above:
NASA's Mars Odyssey, Mars Reconnaissance Orbiter (MRO) and MAVEN OrbiterEurope's Mars ExpressIndia's Mars Orbiter Mission (MOM)the European and Russian partnership ExoMars Trace Gas Orbiter.
The oldest active probe—Mars Odyssey—has been orbiting the planet for 20 years.
The third spacecraft to reach Mars this month is NASA's Perseverance rover, scheduled to land on February 18.

This satellite mockup, seen during antenna testing, shows the shape of ESA's new Proba-V Companion CubeSat, which is due for launch at the end of this year.
The mission is a 12-unit CubeSat—a small, low-cost satellite built up from standardized 10-cm boxes. It will fly a cut-down version of the vegetation-monitoring instrument aboard the Earth-observing Proba-V to perform experimental combined observations with its predecessor.
A pair of antennas for the CubeSat, mounted in this 'structural and thermal model' underwent testing at ESA's Compact Antenna Test Range at the ESTEC technical center in the Netherlands.
"The white patch is a directional high-data rate antenna, needed to downlink large amounts of imagery to users," explains Xavier Collaud of Aerospacelab in Belgium, developing the mission for ESA. "Then the brown patch is an omnidirectional antenna, that—combined with a similar antenna on the other side—allows the reception and transmission of lower-data rate signals in any direction, enabling the control of the mission.
"These antennnas are commercial off the shelf equipment, allowing the building up of small satellites in an affordable, modular manner.

ESA's Solar Orbiter ducks behind the sun
Tuesday, 09 February 2021 12:37
Name: Solar Orbiter, or "Solo' as the mission control team fondly call it, is one of the European Space Agency's pluckiest missions and is now cruising toward the sun.
Age: One year old! We launched on 10 February 2020. Granted, it was first powered up on Earth at some point during construction, but launch is 'when it came alive."
What's it doing out there? It's imaging our star, observing the solar wind and unraveling mysteries of the solar cycle. It's already returned some of the best images of ol'Sol ever, revealing omnipresent miniature solar flares, dubbed 'campfires," near the surface.
Anything else? Well, it uses prehistoric cave pigment as a coating to withstand temperatures up to 520°C. The sun's pretty darn hot, you know.
So, what's happening now? The spacecraft's orbit is taking it behind the sun, and starting a few days ago the apparent angle, as seen from Earth, between Solar Orbiter and the sun started falling below 5 degrees.
