Hope (Emirates Mars Mission)

The Emirates Mars Mission started as a deadline. The United Arab Emirates decided in 2014 to have a spacecraft at Mars for the fiftieth anniversary of the federation, which gave the team six years to build an interplanetary probe in a country that had never built one. The work was led by the Mohammed bin Rashid Space Centre in Dubai, with three American partners: the Laboratory for Atmospheric and Space Physics at the University of Colorado Boulder, Arizona State University, and the Space Sciences Laboratory at the University of California, Berkeley. Arabic Wikipedia puts the team at roughly 200 Emirati engineers working alongside roughly 200 people at the partner institutions, with Omran Sharaf as project manager and Sarah Al Amiri as science lead. The launch happened at 21:58:14 UT on 19 July 2020 from Tanegashima in Japan, which was already the small hours of 20 July in the UAE and breakfast time on 20 July in Japan. Two hundred days later, on 9 February 2021, a 27-minute burn spent about 400 of the 800 kilograms of hydrazine on board and dropped Hope into orbit. The UAE became the fifth entity to put a spacecraft around Mars, after the United States, the Soviet Union, the European Space Agency and India. China's Tianwen-1 arrived the next day and NASA's Perseverance landed nine days later, making February 2021 the busiest month Mars has ever had.

The orbit is the mission, and it is the thing most summaries skip. Almost every Mars orbiter flies low and close to polar: a few hundred kilometres up, sweeping north to south, which resolves boulders but revisits each patch of ground at nearly the same local hour every time. Hope does the opposite. It sits in a 20,000 by 43,000 kilometre ellipse inclined 25 degrees, taking about 55 hours to go round, which is a little over two Martian days. From that height the whole disc fits in the field of view, so its three instruments observe the lower and upper atmosphere as one connected system rather than as a strip of ground. Because periapsis local time drifts as Mars moves around the Sun, the mission builds a full picture of the Martian day in roughly nine to ten days, then repeats it through the seasons. NASA's own catalogue rounds the numbers to about 22,000 by 44,000 kilometres, which is the same orbit described more loosely. The instruments are EXI, a visible and ultraviolet camera; EMIRS, an infrared spectrometer that maps dust, ice cloud, water vapour and temperature; and EMUS, an ultraviolet spectrograph watching hydrogen and oxygen leak into space. The design question they were built to answer is how weather in the lower atmosphere changes what escapes from the top.

The results have justified the geometry. Hope reported forms of Martian aurora nobody had catalogued, including what the team named sinuous discrete aurora, worm-like ultraviolet structures stretching thousands of kilometres from the dayside into the nightside, and patchy proton aurora. It produced daily dust and ice maps across a full Martian year. In its extended mission it went after Deimos, coming within about 100 kilometres, which the UAE Space Agency describes as the closest approach since Viking in 1977; the observations included the first extreme and far-ultraviolet measurements of the moon and the first hyperspectral thermal infrared data, and the team argued they favour Deimos forming from Mars over the older idea of a captured asteroid. All of it is meant to be public. The mission's Science Data Center releases data on a six-month cadence, free to anyone with an account. How much has come back depends on who you ask and in what unit. A July 2026 roundup says more than 10 terabytes across 16 released batches, more than 35 peer-reviewed papers and more than 200 institutions using the data. AFP, reporting the February 2026 announcement, quoted a target of one terabit and an outcome of ten terabits. Arabic Wikipedia gives 5.4 terabytes by April 2025. These are not reconcilable as written, and we have not found a source that reconciles them.

As of 23 August 2026 the mission is alive on the operator's word, which is the strongest evidence available and worth stating plainly rather than dressing up. On 17 February 2026, at a press conference in Dubai, Ahmad Belhoul Al Falasi, the UAE Minister of Sport and chairman of the UAE Space Agency board, announced a three-year extension to 2028; Aviation Week covered it again on 1 May 2026, and the UAE Space Agency's own mission page carries a Mission Extension section. A six-year roundup on 19 July 2026 described the spacecraft as still delivering and revealed that Hope had also pointed EXI and EMUS at interstellar comet 3I/ATLAS. JPL Horizons serves Mars-centred vectors for Hope, target -62, from an orbit solution that Horizons says is fit to tracking data through 28 May 2026 and predicted after that. Today's numbers are a prediction rather than a fix, but the fit date is itself evidence: JPL was still tracking the spacecraft in late May 2026. Against that, one thing does not fit the picture of a fully current mission: the Science Data Center's public news page, checked today, has announced nothing since 10 September 2025, when Release 16 made observations up to 28 February 2025 available. On a six-month cadence, two further releases would be due by now. That may simply be a website nobody has updated. We flag it because the alternative reading matters, and we could not test it without creating an account.

Hope's real legacy may be institutional rather than scientific. A country with no interplanetary heritage went from decision to Mars orbit in under seven years, and it did so by buying expertise rather than hardware: the partner laboratories in Colorado, Arizona and California trained and worked alongside Emirati engineers who did the building, rather than delivering a finished spacecraft to be flown. The data policy followed the same logic. Everything goes to a public archive that any researcher can register for, and the mission counts more than 200 institutions using it and more than 35 peer-reviewed papers written from it, which is a far larger scientific footprint than a single 550 kg orbiter would normally generate. The next Emirati deep-space mission, to the asteroid belt, is scheduled for 2028, the same year the Hope extension runs out, and the July 2026 six-year roundup frames the extra three years partly as a way to keep the operations team current for it. Whether the spacecraft physically lasts that long is a separate question from whether it is funded to. Its orbit is high enough that atmospheric drag is irrelevant on any human timescale, so the real limits are hydrazine for attitude control, solar panel and battery degradation, and the continued attention of a team that will soon have a second interplanetary spacecraft to fly. On today's evidence none of those has run out.
