The Roman observatory will travel to the Sun-Earth Lagrange point 2, or L2, about one million miles from Earth, where the Sun’s and Earth’s gravity balance out, to complete a statistical census of planetary systems in our galaxy and settle essential questions in the areas of dark energy, exoplanets, and infrared astrophysics.Roman Space Telescope Plaque Install NASA ID: KSC-20260728-PH-JMT01_0001 Technicians inside the Payload Hazardous Servicing Facility at NASA’s Kennedy Space Center complete installation of a commemorative plaque on the agency’s Nancy Grace Roman Space Telescope, as photographed on Tuesday, July 28, 2026.

Last week was my first time aboard R/V Roger Revelle, named for the legendary Scripps Oceanography scientist who warned the world about the link between CO2 and a warming planet. This ship has carried scientists across the globe for three decades to advance understanding of the ocean and our planet.

Here's a pre-Mariner IV crewed Mars lander scheme, which assumed an atmosphere 10% as dense as Earth's (typically carbon dioxide detected from Earth was expected to be a minority component of a mostly nitrogen atmosphere). spaceflighthistory.blogspot.com/2015/09/the-...

In the summer of 1965, the Mariner IV flyby mission revolutionized our understanding of the planet Mars. Among other things, it rendered obsolete our old plans for Mars landers. spaceflighthistory.blogspot.com/2015/09/the-...

CNSA’s Tianwen-1 mission has recently released new images of Mars, including this view of the Charitum Montes in the southern rim of Argyre Planitia. Full size 6K & more info: flic.kr/p/2ssvpEm Image Processing: Andrea Luck Raw data: CNSA/CLEP/PEC/MoRIC Mosaic of 4 images 2025-12-04 235km altitude

A satellite view of the Charitum Montes mountain range, with rusty brown peaks and ridges contrasting against more soft cream coloured plains. Bright seasonal frost blankets much of the slopes in varying intensity altering the usual rusty reddish colour of mars and contrasting with dark valleys and scattered impact craters.

Friday I leave for Oslo on the first leg of an expedition I’m leading to Greenland for the total solar eclipse. We will board ship in Svalbard to eventually enter Scorsby Sund in Greenland where our path will align with the sun and moon on August 12. Here’s the poster I designed. #astronomy #art

Sadly it's not just #JodrellBank losing funding, with deep cuts across the board for UK astronomy. One example is the HiPERCAM project whose funding has been entirely cut to save £50K/yr - peanut-levels of £s. Spectacular fast transient science lost, for what? 🔭😡 www.zmescience.com/science/astr...

SSL's Weijie Sun & Jiutong Zhao, along with @umichengineering.bsky.social's Ryan Dewey, analyzed MESSENGER mission data and found that Mercury has intermittent radiation belts. The findings could help protect the @esa.int/JAXA BepiColombo mission when it reaches Mercury this year.

Mercury has part-time radiation belts

Scientists thought Mercury's magnetic field was disrupted by the sun too often to trap a radiation belt, but new analysis of MESSENGER data says that's not always the case.

I'm absolutely devastated for colleagues at Jodrell Bank who found out this morning that funding for the UK's e-MERLIN radio telescope array will be terminated. This is a short-sighted move, to save a tiny fraction of the overall UK science budget. #SaveJodrellBank 🔭🧪 www.bbc.co.uk/news/article...

“What will the Lovell Telescope discover/enable 20 yrs from now? I can’t tell you, and that’s the point. It will either be something extraordinary that none of us can yet predict, or we will defund it and leave Cheshire with a rusting monument to unfulfilled potential and discoveries never made.” 🔭🧪

In the 1990s, thanks to The Planetary Society, my name joined countless others on a CD-ROM attached to the Cassini spacecraft, whose atoms are now a part of Saturn. I made my partner’s day recently when I told her that our names will soon be heading out to Lagrange Point 2, a million miles away!
