In Quest to Reach Alpha Centauri, Breakthrough Starshot Launches World's Smallest Spacecraft

"Breakthrough Starshot, a multi-faceted program to develop and launch practical interstellar space missions, successfully flew its first spacecraft -- the smallest ever launched. On June 23, a number of prototype "Sprites" - the world's smallest fully functional space probes, built on a single circuit board -- achieved Low Earth Orbit, piggybacking on OHB System AG's 'Max Valier' and 'Venta' satellites. The 3.5-by-3.5 centimeter chips weigh just four grams but contain solar panels, computers, sensors, and radios. These vehicles are the next step of a revolution in spacecraft miniaturization that can contribute to the development of centimeter- and gram-scale "StarChips" envisioned by the Breakthrough Starshot project."

NASA finally admits it doesn't have the funding to land humans on Mars, Ars Technica

"Now, finally, the agency appears to have bended toward reality. During a propulsion meeting of the American Institute for Aeronautics and Astronautics on Wednesday, NASA's chief of human spaceflight acknowledged that the agency doesn't really have the funding it needs to reach Mars with the SLS rocket and Orion spacecraft. These vehicles have cost too much to build, and too much to fly, and therefore NASA hasn't been able to begin designing vehicles to land on Mars or ascend from the surface. "I can't put a date on humans on Mars, and the reason really is the other piece is, at the budget levels we described, this roughly 2 percent increase, we don't have the surface systems available for Mars," said NASA's William H. Gerstenmaier, responding to a question about when NASA will send humans to the surface of Mars. "And that entry, descent and landing is a huge challenge for us for Mars."

"And of course none of these Mars missions in the 2030s are in any budget - notional, proposed, or projected - that means anything to anyone actually working at NASA today. So it is hard to blame people who can't give you a straight answer. Just look at what their management has given them to work with - and what the agency has had to work with in terms of guidance from Congress and the White House. Just in the past 10-12 years NASA has veered away from the shuttle towards the Moon, then away from the ISS to Mars and away from the Moon and back to ISS, and now back to Mars (and maybe the Moon) and also some boulder on an asteroid."
