He is a space historian and the author of Jonathan\u2019s Space Report. And he\u2019s concerned about the consequences of humanity\u2019s presence in Earth-orbit, about how we\u2019re already polluting our new home in space. McDowell has said:<\/p>\n<blockquote>\n<p>The track record of the human species is not that great. All of these issues that cause us trouble here on Earth, we\u2019re going to export them into space. That\u2019s just the way it is.<\/p>\n<\/blockquote>\n<p>As an illustration, the first satellite \u2013 Sputnik \u2013 was launched to Earth-orbit in 1957. Then for decades, the world was shooting around 150 objects per year \u2013 satellites, probes and landers, crew capsules, space station modules \u2013 into Earth-orbit. <\/p>\n<p>But, in 2017, everything changed. The number of launches skyrocketed. In 2023, humanity flung 2,664 objects into Earth-orbit. Almost all of them are still up there. NASA\u2019s Orbital Debris Program Office estimates there are more than 25,000 objects drifting free in Earth-orbit 4 inches (10 cm) or larger. Nearly 500,000 smaller bits of space junk \u2013 0.4 to 4 inches (1-10 cm) \u2013 and 100 million microscopic particles pepper low Earth orbit. In 2022, their mass exceeded 19.8 million pounds (8.9 million kg).<\/p>\n<p>McDowell put the possible danger plainly in the HBO documentary Wild, Wild Space.

McDowell is the author and editor of Jonathan\u2019s Space Report, an email-distributed newsletter documenting satellite launches. McDowell\u2019s main research interests include: the cosmological microwave background; the X-ray emission from the merging galaxy Arp 220; the nature of the broad emission line region in quasars; the broad-band spectral energy distribution in quasars; and studying nearby galaxies with the Chandra X-ray Observatory. In software, McDowell helped design the CIAO data analysis package and the software infrastructure for the Chandra data processing pipelines. More recently, McDowell led the creation of an exhibit of astronomical images at the Smithsonian. Minor planet (4589) McDowell is named after him.
