As new probes reach Mars, here's what we know so far from trips to the red planet
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.
Keeping it fluid: Probing how fluids behave in weightlessness
NASA astronaut Victor Glover installs the Fluid Dynamics in Space experiment, or Fluidics for short. Fluidics is the black cylinder pictured in the foreground of the European Columbus module of the International Space Station.
Developed by French space agency CNES and co-funded by Airbus, the Fluidics experiment is probing how fluids behave in weightlessness.
The experiment is made up of six small, transparent spheres housed in the black centrifuge seen here and is studying two phenomena.
The first is 'sloshing' or how liquids move inside closed spaces, which is hard to predict both with and without gravity. Think how frustrating it can be to get the last drop out of a packet of orange juice, then imagine the challenge for engineers designing satellites to use every drop of fuel in weightlessness, or designing rockets with fuel tanks that must deliver fuel to the engines under extreme loads. Insights can help industry design better satellite fuel-systems to increase their life and make them less expensive.
A second part of the experiment looks at wave turbulence in liquids. On Earth, gravity and surface tension influence how energy dissipates in waves or ripples.

Meet ESA’s R&D department
Our new brochure introduces ESA’s R&D department: the engineers charged with inventing the new technologies needed for Europe to push further out into space, and develop the novel services improving our lives here on Earth.
ESA's Solar Orbiter ducks behind the sun
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.
Russian cosmonauts to test new shielding material for radiation protection
An award-winning composite material that has proven effective against radiation in nuclear submarines will be sent to the orbital outpost for further testing this year, the Russian space agency said on Monday. "Space is known for its elevated radiation levels... The invention has already been tested in nuclear subs. If the space experiment proves to be equally successful the material will
China tests its missile interception equipment
China conducted a land-based, midcourse missile interception test on Thursday-the fifth land-based, anti-ballistic missile test the country has publicly announced. The Defense Ministry said in a brief statement late on Thursday that the test had achieved its goals, and the operation was defensive in nature, not targeting any other country. Before the latest operation, China had succe
DARPA pursues plan for robust manufacturing in space
As commercial space companies increase the cadence of successful rocket launches, access to space is becoming more routine for both government and commercial interests. But even with regular launches, modern rockets impose mass and volume limits on the payloads they deliver to orbit. This size constraint hinders developing and deploying large-scale, dynamic space systems that can adapt to change
NATO picks France's Toulouse for new military space 'Center of Excellence'
While the North Atlantic Treaty Organization (NATO) has disavowed an interest in militarizing space, several members of the alliance, including the US, UK, and France, have oriented themselves toward conflict in the space domain in recent years. The North Atlantic alliance has selected the French city of Toulouse to host its new higher education center for military space affairs. NAT
Study of supergiant star Betelgeuse unveils the cause of its pulsations
Betelgeuse is normally one of the brightest, most recognizable stars of the winter sky, marking the left shoulder of the constellation Orion. But lately, it has been behaving strangely: an unprecedentedly large drop in its brightness has been observed in early 2020 (Figure 1), which has prompted speculation that Betelgeuse may be about to explode. To find out more, an international team of
