SpaceX Starship launch today live: When and how to watch biggest ever rocket lift off

The SpaceX rocket stands tall on its launch pad on a sunny day in Texas, USA

Elon Musk’s SpaceX is set to launch its Starship spacecraft and Super Heavy rocket system for the first time from the Texas Starbase, USA.

The spaceflight system is designed to carry crew and cargo to Earth’s orbit, with the aim of carrying astronauts to the Moon and Mars – including use in NASA’s Artemis 3 mission to the Moon in 2025.

But today there is no crew and it won’t reach orbit. It instead marks the first fully integrated test flight of the rocket system after successful tests of the capsule and rocket individually.

This flight aims to demonstrate Super Heavy’s ‘soft-landing’ as it hovers above the ocean just before splashdown. It will also help SpaceX test and improve the system’s design ahead of missions like Artemis 3.

When is it launching?

Starship is scheduled to launch today, Monday 17 April at 2pm BST and 8am CT/9am ET/6am PT.

The SpaceX livestream will begin 45 mins before the expected launch time. Unlike last week’s JUICE launch, which had a one-second window during which the European Space Agency could attempt lift-off, SpaceX have 150 minutes to launch Starship and Super Heavy.

SpaceX could therefore wait to launch any time within the launch window (1pm to 3:30pm BST) depending on weather. The SpaceX Twitter Feed will share new timing updates if the launch time changes from the expected lift-off at 2pm BST.

In the US, the launch window is between:

  • 7am to 9:30am CT (central – the local time at Starbase in Texas)
  • 8am to 10:30am ET (eastern)
  • 5am to 7:30am PT (pacific)

If the launch attempt is not successful today then SpaceX will try again on 18 April and 19 April.

How can I watch it?

Live coverage will begin at 1:15pm BST and 7:15am CT/8:15am ET/5:15am PT. It can be watched on the SpaceX YouTube channel or on the livestream below.

NASA Space Flight will also provide live coverage here.

What is SpaceX Starship?

Starship is a fully reusable spacecraft designed by Elon Musk’s space transportation company SpaceX. It is also capable of transportation on Earth and can complete any point-to-point journey in under an hour.

‘Starship’ also refers to the combined transportation system that consists of the Starship spacecraft and the Super Heavy rocket. The “most powerful launch vehicle ever developed” according to SpaceX, Starship will be able to carry a crew of up to 100 and cargo with a payload capacity of 400 metric tonnes.

Starship will circle Earth (but not reach orbit) at an altitude of 234km before splashdown in the Pacific Ocean, near Hawaii.

The Super Heavy booster will return separately, splashing down in the Gulf of Mexico – 32km from the launch site. Though Starship is fully reusable, for this mission SpaceX will not recover Starship or the Super Heavy booster.

Why are our knees so prone to injury?

Image
The bottom of your thigh bone sits on top of the shin bone, and the joint is held together by ligaments and muscles that can easily be sprained and torn. As well as being structurally less stable, the knee joint is also far more restricted as it can only move forwards and backwards with a very limited amount of twisting. The moment the knee is no longer aligned with the foot, it relies on the ligaments and muscles for stability – which can easily be pushed too far and cause injury.

Semaglutide: How the ‘skinny jab’ could help treat obesity

Image
“The worst kept secret in Hollywood!” shout the headlines. This particular badly-kept secret involves a pricey new weight-loss drug called Semaglutide. If you take the glossy celebrity magazines at face value, fans of these $1,200-a-month injections include Kim Kardashian and Elon Musk. But in mid-February, the weight-loss treatment moved beyond the A-list when UK high-street chemists announced they would be selling Semaglutide injections from spring 2023. At the time of writing, the UK price had not been disclosed. So what is Semaglutide? Is it safe? And could it be a game-changer for tackling the broader public health crisis of obesity? What is Semaglutide? Semaglutide is manufactured by the Danish pharmaceutical giant Novo Nordisk, and sold under the names Ozempic and Wegovy. Ozempic, in particular, made international headlines last year after going viral on TikTok, with the #MyOzempicJourney trend showcasing scarcely believable body transformations. Wegovy is the one going on ...

In Pictures: Euclid sends back first test images

Image
The first test images produced by ESA’s Euclid probe are here and hint at the amazing power of the imaging power on board. These test images are simply just that – future images will be even more detailed and much sharper and cleaner. The Euclid Telescope has been built and designed by ESA and the Euclid Consortium to explore the evolution of the dark universe, discovering how it formed and expanded over time. In order to do this, it has been fitted with a 1.2m-diameter telescope, visible-wavelength camera, and near-infrared camera/spectrometer. Using these instruments, Euclid will build a detailed 3D map of the Universe – the third dimension being time. During its mission, Euclid aims to answer some pretty big questions, such as if the expansion of our Universe is uniform or whether it changes over time. And whether or not our understanding of gravity is complete and accurate. The Near-Infrared camera This raw image was taken by Euclid’s Near-Infrared Spectrometer and Photom...
