With an internal global ocean twice the size of Earth’s oceans combined, Jupiter’s moon Europa carries the potential for conditions suitable for life. But the frigid temperatures and the nonstop pummeling of the surface from Jupiter’s radiation make it a tricky target to explore: Mission engineers and scientists must design a spacecraft hardy enough to withstand the radiation yet sensitive enough to gather the science needed to investigate Europa’s environment.

The Europa Clipper orbiter will swoop around Jupiter on an elliptical path, dipping close to the moon on each flyby to conduct detailed reconnaissance. The science includes gathering measurements of the internal ocean, mapping the surface composition and its geology, and hunting for plumes of water vapor that may be venting from the icy crust.

SPARKS, Nev. (KOLO) — Their headquarters sits on a hill overlooking east Sparks, but Sierra Nevada Corporation’s sights are set much higher.

Long known for the development of high-tech equipment for applications here on Earth, they are also a major player in space exploration and research.

They provided some key parts to the latest Mars rover, Perseverance, and in a virtual press conference from their plant in Colorado Wednesday they announced an ambitious timeline for their latest projects—commercial flights with its Dreamchaser spaceplane to the International Space Station next year…and by 2028, a replacement for the space station itself.

An ancient crater lake in the southern highlands of Mars appears to have been fed by glacial runoff, bolstering the idea that the Red Planet had a cold and icy past.

Shooting beams of ions at proton clouds may help researchers map the inner workings of neutron stars.

Physicists at MIT and elsewhere are blasting beams of ions at clouds of protons —like throwing nuclear darts at the speed of light — to map the structure of an atom ’s nucleus.

Virgin Galactic passengers won’t circle Earth like astronauts aboard the International Space Station do. But they will get to experience a few minutes of weightlessness and see the curve of Earth against the blackness of space. More than 600 people have booked a ride to date, at a price (most recently) of $250000 per seat, company representatives have said.

Distribution bots.

Boston Dynamics is best known for its robot dog Spot, a machine designed to work in a range of environments, from offshore oil rigs to deep underground mines. But in recent years, the company has increasingly focused attention on the logistics space, and today is unveiling a new robot with just one application in mind: moving boxes in warehouses.

The robot is called Stretch and looks relatively dull for a Boston Dynamics creation. It’s not modeled after humans or animals, and instead aims to be as practical as possible. It has a square mobile base containing a set of wheels, a “perception mast” with cameras and other sensors, and a huge robotic arm with seven degrees of freedom and a suction pad array on the end that can grab and move boxes up to 23 kilograms (50 lbs) in weight.

Desert sighting.

While taking images of its new surroundings on the arid Martian surface, the Perseverance rover recently spotted a dust devil whirling by in the distance.

On March 28, 2021 NASA’s Mars Helicopter Ingenuity took vertical position (upright) under Perseverance Rover at Helipad. Helicopter release system unlocked yesterday. Today ingenuity made one more step to be deployed from Perseverance. As for now, NASA’s rover prepares to unlock Helicopter’s landing legs and put it on the Mars’s surface. Flight scheme is known. Solar panel charges Lithium-ion batteries, providing enough energy for one 90-second flight per Martian day (~350 Watts of average power during flight). Atmospheric weather relates to conditions such as air density at flight time, which affects the thrust that can be produced by the rotor and could result in adjustments of flight parameters. Temperature and wind profiles during the day are used to estimate the energy required to operate heaters. Winds at the time of the flight are tied to risks associated with takeoff, landing, and flying in high winds or very gusty conditions. All the things that a pilot on Earth would care about too!
