The next SpaceX launch is Falcon Heavy | Nancy Grace Roman Space Telescope, flown by SpaceX from Launch Complex 39A, Kennedy Space Center, FL, USA, lifting off at 2026-08-30 11:26:00Z. 16 SpaceX launches are currently on the manifest below, each with a live countdown, its pad, its vehicle and a plain statement of how firm the date actually is. This one is filed to the minute.
The Nancy Grace Roman Space Telescope is a NASA infrared space telescope with a 2.4 m (7.9 ft) wide field of view primary mirror and two scientific instruments. The Wide-Field Instrument (WFI) is a 300.8-megapixel multi-band visible and near-infrared camera, providing a sharpness of images comparable to that achieved by the Hubble Space Telescope over a 0.28 square degree field of view, 100 times larger than imaging cameras on the Hubble. The Coronagraphic Instrument (CGI) is a high-contrast, small field of view camera and spectrometer covering visible and near-infrared wavelengths using novel starlight-suppression technology. Roman objectives include a search for extra-solar planets using gravitational microlensing, and probing the expansion history of the Universe and the growth of cosmic structure, with the goal of measuring the effects of dark energy, the consistency of general relativity, and the curvature of spacetime.

Questions about the schedule
FAQ / 01
BRIEF
How accurate are launch times?
It depends on how precisely the operator has filed the flight, and every launch on this page is labelled with that precision. A launch marked T-0 SET is accurate to the minute or better and is worth setting an alarm for. One marked NET ±1 DAY, ±1 WEEK or coarser is a placeholder: the date will move. As a rule, times firm up inside the final 48 hours, and the last unknown is usually weather.
FAQ / 02
BRIEF
Why do launches slip?
Four reasons cover almost all of it: weather at the pad or in the booster recovery zone, a range conflict with another user of the same airspace or sea lane, a failed check on the vehicle or the payload during the count, and orbital mechanics. A rendezvous with the International Space Station has a window measured in seconds, so missing it costs a full day. Slips of hours to weeks are routine and rarely mean anything is wrong.
FAQ / 03
BRIEF
Which agencies and operators are covered?
All of them. SpaceX, United Launch Alliance, Rocket Lab, Arianespace, Blue Origin and Firefly; the state programmes CASC, Roscosmos, ISRO and JAXA; and the newer Chinese commercial operators such as Galactic Energy and LandSpace. The manifest comes from Launch Library 2, which tracks orbital launches worldwide, and this page lists whatever is scheduled with no editorial filter.
FAQ / 04
BRIEF
How often does this manifest update?
Delta-V re-reads the upstream launch manifest every fifteen minutes and re-renders this page with it, so a scrub, a new target date or a fresh T-0 appears here within about a quarter of an hour of the operator filing it. The countdowns do not wait on that: each one ticks live in your browser against the published launch time, down to the second inside the final hour.
Launch data from The Space Devs Launch Library 2. Times are UTC and are No Earlier Than values: an operator can move a launch at any point, and frequently does.
