    Did you watch ? Even though the Olympic torch has been extinguished, we’re looking for our own kind of torch – a Lunar TORCH. Read below to learn how you can design a heliostat, which will reflect solar light where it is most needed for astronauts:

    When we collect solar power for living & working on the Moon, we’ll also need a way to store and distribute it. We recently awarded $500K to imagine a next-gen energy infrastructure on the Moon. , passing the 🔥 – how else can people get involved in upcoming missions?

    We could use my energy to power instruments. Just like I power solar arrays on existing satellites, my energy could be redirected to power surface instruments in the dark! , passing the 🔥 – what other technologies will we need to harness my power for the Moon?

    When new spacecraft come to visit, it would be nice to have a way to guide them in! A heliostat is like a lighthouse, providing a visual beacon for spacecraft navigation systems. , passing the 🔥 – how can we use your energy to help power instruments with a heliostat?

    Not every part of the Moon is reached by the Sun. Sometimes, we need to use a heliostat to reflect light to another area where astronauts might be working shrouded in shadow. , passing the 🔥 – how else could we use a heliostat?

    Today is the closing ceremony for , where the Olympic torch will be extinguished. We also need a “torch” at the Moon, and we want you to design it! 👀: , passing the 🔥– how would a heliostat, or “Sun reflector,” help surface ops?

    It’s ! ☀️ In its youth, the Sun shaped our planet’s atmosphere and the development of life on Earth. Researchers are using a stellar analogue — similar to the young Sun — to understand what the Sun may have been like in its early years.

    ✨🔭 Thanks to , we are given mind-boggling views into thousands of galaxies. But how does a telescope the size of a school bus orbiting 340 miles above Earth capture these images of deep space? We break it down step by step:

    This image is Hubble's Ultra Deep Field which is the deepest visible-light portrait of our universe. This astonishing display of nearly 10,000 galaxies was imaged over the course of 400 Hubble orbits around Earth, with a total of 800 exposures captured over 11.3 days.

    is one of my most complicated tasks. Early pics and data show a successful drill hole, but no sample in the tube–something we’ve never seen in testing on Earth. Mars keeps surprising us. We’re working through this new challenge. More to come.

    Coming soon to an orbit near the Moon. 🌔 Our CAPSTONE 🛰️ launches from New Zealand later this year to demonstrate new navigation technologies in space, and test a unique lunar orbit for the future outpost . Latest updates:

    CAPSTONE’s 12-Unit CubeSat with the spacecraft’s S-Band antenna shown on the right side. The 16 square-shaped elements on the surface of the flat plate are low-profile antennas, called patch antennas, that make up the S-Band antenna array. The antenna is integrated with the communications system structure. The red structures are handling fixtures that will be removed from the spacecraft prior to testing.
