I originally joined twitter just to follow @NASA. I tweet mostly NASA & Space related photos I take in my travels. Photos are (c) @CaptainBJones.

ALT In a photo from the 1970s, engineers gather around one of the Voyager spacecraft before it was launched.
ALT Graphic titled “ARISS Frequencies.” A NASA image of the International Space Station orbiting above Earth appears on the left. The right side lists amateur radio frequencies used on the ISS as of June 2026. The ARISS FM voice repeater transmits on 437.800 MHz and listens on 145.990 MHz using a 67 Hz CTCSS tone. Packet radio (UHF APRS) transmits and listens on 437.825 MHz. ARISS STEM educational contacts use 145.800 MHz FM for transmissions from the ISS. The ARISS logo appears in the lower-right corner. NASA image credit noted at bottom.
ALT Graphic titled “Ham Antennas on the ISS.” Text explains that ARISS antennas on the Columbus Module support 2-meter, 70-centimeter, L-band, and S-band operations. The main image shows part of the International Space Station’s Columbus Module above Earth, with one of the ARISS amateur radio antennas visible extending from the module. An inset close-up highlights the antenna. Additional text notes that the image shows one of three Columbus Module antennas and that a group of four antennas is located on the ISS Service Module. ARISS logo and NASA photo credit appear in the lower right corner.
ALT Graphic titled “STS-57 Memories.” On the left, a close-up photo shows a space shuttle crew member inside the shuttle cockpit wearing a headset and holding radio equipment, with control panels and cables visible in the background. The shirt reads “SAREX.” On the right, text reads: “June 21 – July 1 1993 flight of Endeavour was a SAREX mission. The Shuttle Amateur Radio Experiment was carried aboard this flight, with pilot Brian Duffy (N5WQW) and mission specialist Janice Voss (KC5BTK) taking part. President Clinton commended the SAREX activities during a call with the crew in space: ‘You may be on this mission creating thousands of scientists for the future, just by the power of your example and by this direct communication.’” An ARISS logo appears at the bottom right.
ALT Sally Ride, first American woman in space, smiles inside Space Shuttle Challenger during the STS-7 mission in June 1983.
ALT A full disk image of Earth, as seen from the Orion capsule. The planet is a pale blue, swirling with white clouds and glowing slightly lighter blue in place from reflected light. From about 8 to 9 o'clock, a large brown landmass is Africa, with the Iberian peninsula twinkling with lights just where the planet curves. At the 1 o'clock spot, aurora glow in a thin green glow, just barely separated from the planet's surface. Earth is set against the black of space. Credit: NASA/Reid Wiseman
ALT On a snowy March 16, 1926, Dr. Robert H. Goddard rests his hand on the testing frame supporting his liquid fuel rocket at Ward Farm in Auburn, Massachusetts. A wooden door is propped up at an angle next to the frame where Goddard\u2019s assistant, Henry Sachs, later sheltered after lighting the rocket.
