"Professor Goddard does not know the relation between action and reaction and the need to have something better than a vacuum against which to react. He seems to lack the basic knowledge ladled out daily in high schools."
--1921 New York Times editorial about Robert Goddard's revolutionary rocket work.

"Correction: It is now definitely established that a rocket can function in a vacuum. The 'Times' regrets the error."
NY Times, July 1969.

NASA’s Lucy Spacecraft Images Asteroid Donaldjohanson

Wed, 04/23/2025 - 9:50am
The asteroid Donaldjohanson as seen by the Lucy Long-Range Reconnaissance Imager (L’LORRI). This is one of the most detailed images returned by NASA’s Lucy spacecraft during its flyby. This image was taken at 1:51 p.m. EDT (17:51 UTC), April 20, 2025, near closest approach, from a range of approximately 660 miles (1,100 km). The spacecraft’s closest approach distance was 600 miles (960 km), but the image shown was taken approximately 40 seconds beforehand. The image has been sharpened and processed to enhance contrast.

Sixty Years in Canberra: NASA’s Deep Space Network

Tue, 04/08/2025 - 3:36pm
This March 4, 2020, image shows Deep Space Station 43, a 70-meter-wide (230-feet-wide) radio antenna at NASA’s Deep Space Network facility in Canberra, Australia. The facility celebrated its 60th anniversary on March 19, 2025, while also breaking ground on a new radio antenna. The pair of achievements are major milestones for the network, which communicates with spacecraft all over the solar system using giant dish antennas located at three complexes around the globe.

X-ray Clues Reveal Destroyed Planet

Wed, 04/02/2025 - 1:10pm
In about 5 billion years, our Sun will run out of fuel and expand, possibly engulfing Earth. These end stages of a star’s life can be utterly beautiful – as is the case with this planetary nebula called the Helix Nebula. Astronomers study these objects by looking at all kinds of light. This images show X-rays from NASA's Chandra X-ray Observatory (magenta), optical light data from NASA's Hubble Space Telescope (orange, light blue), infrared data from the European Southern Observatory VISTA telescope (gold, dark blue), and ultraviolet data from GALEX (purple) of the Helix Nebula.
