While a Mars rover can explore where no person has gone before, a smaller robot at the University of the Sunshine Coast in Australia could climb to new heights by mimicking the movements of a lizard.
Simply named X-4, the university’s climbing robot has allowed a team of researchers to test and replicate how a lizard moves in the hope that their findings will inspire next-generation robotics design for disaster relief, remote surveillance and possibly even space exploration.
In a scientific paper published today in Proceedings of the Royal Society B, the team states that lizards have optimized their movement across difficult terrain over many years of evolution.
China has a good chance of becoming the dominant space power in the 21st century, and it’s not just looking to copy NASA on the way to the top. Instead, it’s paying close attention to innovative US companies like SpaceX, writes Eric Berger.
Great new episode with Michael Seiffert, the NASA project scientist for the U.S. contribution to the European Space Agency’s Euclid spacecraft. Seiffert talks candidly about what it takes to strike a balance between risk and reward in the design of this upcoming $1 billion dollar dark energy mission.
Fascinating new chat with Michael Seiffert, the NASA project scientist for the U.S. contribution to the European Space Agency’s Euclid spacecraft. Due for launch in the second half of 2022, we discuss how this new space telescope will help astronomers finally understand the mystery of dark energy and maybe even dark matter.

She previously interned at ESA’s European Astronaut Center and NASA’s Johnson Space Center.
Company officials say it will likely be summer before the ship begins glide flight testing at Spaceport America in southern New Mexico.
Virgin Galactic has reached space twice before — the first time from California in December 2018. The company marked its second successful glide flight over Spaceport America last June.
Virgin Galactic is one of a few companies looking to cash in on customers with an interest in space. Jeff Bezos’ Blue Origin launched a new capsule in January as part of test as it aims to get its program for tourists, scientists and professional astronauts off the ground.

Space travel nowadays relies on physical ejection of propellants, which is challenged by reachable distance of a vehicle in desirable time. In contrast, electromagnetic propulsion was proposed to be a potential solution without need of carrying bulky mass of propellants, by using force interaction of local magnetic dipoles with the external natural magnetic field. Further development of this technique, however, has been daunted by extremely small magnetic induction that can be obtained.
To generate a significant thrust by a system with a reasonable scale, we propose an alternative concept of design, based on the variation of local magnetic dipole moments that has not been considered.
A magnetic dipole is created by wrapping a solenoid around an iron core. It is varied spatially by changing the cross-sectional area of the solenoid, hence giving a gradient of magnetic dipole moment. The interaction force is measured by an in-house force sensor based on a cantilever, which has a high sensitivity of one micro-Newton. In addition, numerical simulation is used to calculate the magnetic field and created force via the Maxwell stress tensor.
When SpaceX launches four civilian astronauts on the private Inspiration4 spaceflight, they’re going to have the ultimate window: a glass dome offering panoramic views of Earth from space.
While SpaceX’s Crew Dragon spacecraft for the mission is already equipped with flat windows, the Inspiration4 mission — which is set to launch later this year with billionaire Jared Isaacman, who chartered the flight with SpaceX, commanding the crew — will include a unique domed window, allowing crew members to get a 360-degree view of their surroundings. That new window, and the Inspiration4 mission’s full crew, were announced in a press conference today (March 30).
WASHINGTON — As SpaceX gears up for another test flight of a Starship prototype, the Federal Aviation Administration is facing new scrutiny from Congress for how it handled SpaceX’s violation of its launch license on an earlier test flight.
SpaceX had planned to launch its SN11 Starship vehicle March 29 from its Boca Chica, Texas, test site. That flight will be similar to those of previous Starship prototypes, going to an altitude of 10 kilometers before landing on a nearby pad.
However, SpaceX called off the March 29 launch attempt because an FAA inspector could not arrive to observe the flight during a five-hour window. “FAA inspector unable to reach Starbase in time for launch today,” tweeted Elon Musk, chief executive of SpaceX, using the proposed new name for the Boca Chica site. “Postponed to no earlier than tomorrow.”
