At 3:45 p.m. Tuesday, Eastern Time (2045 UTC), the SpaceX Falcon Heavy rocket launched from Kennedy Space Center in Florida, United States. Its cargo: a US$100,000 Tesla sportscar, the personal property of SpaceX CEO Elon Musk, which he hopes will soon be in its own orbit around the Sun. This is the most powerful rocket since the Saturn V of Project Apollo was retired in 1970. The rocket is meant to follow a course called a Hohmann transfer orbit.

“It’ll be a really huge downer if it blows up,” Musk told the press the day before the launch, but went on to say, “If something goes wrong, hopefully it goes wrong far into the mission so we at least learn as much as possible along the way. I would consider it a win if it just clears the pad and doesn’t blow the pad to smithereens. That’s four million pounds of TNT equivalent so there’s probably not going to be much left if that thing lets loose on the pad.” The car was equipped with a fully space-suited dummy, cameras to monitor its trip into space, a copy of Douglas Adams’ Hitchhiker’s Guide to the Galaxy, and a radio blasting Space Oddity by David Bowie.

The Falcon Heavy has a total of 27 engines and stands 230 feet (70.1 m) tall. According to SpaceX, the Falcon Heavy uses three boosters, the same kind as the company’s smaller cargo rockets. After the rocket exited the Earth’s atmosphere, two of these boosters detached from the main body of the rocket and, in a first for space technology, were successfully guided back down to the landing pad about ten minutes after launch. The third was to have landed on a drone ship, but missed by around 100 yards (about 90 meters) and hit the ocean “at around 200 miles per hour,” according to Musk. The reusability of the boosters makes an enormous difference in the cost of the launch.

Even the relatively heavy-hauling U.S. Space Shuttle program, which was closed in 2013, did not rely on rockets as powerful as those used in Project Apollo, the program in which NASA, the U.S. Government space agency, sent manned missions to the Moon in the 1960’s and 70’s. Most recent space projects have focused on smaller, lighter machinery, such as Scaled Composites’ SpaceShipOne in 2004, which reached space after being carried part of the way by a carrier jet instead of launching from the ground. As of last week, the most powerful rocket in use was the Delta IV, operated by the United Space Alliance. It costs about US$435 million per launch, while SpaceX says the Falcon Heavy will cost US$90 million per launch.

NASA is also working on a heavy-duty rocket, the Space Launch System, but there have been delays.

The Independent Monitoring Commission has reported that the Provisional Irish Republican Army has undergone major changes within their military structure and shows that the IRA Army Council wants to put its military campaign behind it. The Commission consists of John Alderdice, a former Alliance Party leader; Joe Brosnan, former Secretary General of the Department of Justice, Republic of Ireland; John Grieve, former Deputy Assistant Commissioner of the Metropolitan Police and former head of the Metropolitan Police Anti-Terror Branch; and Dick Kerr, former Deputy Director of Central Intelligence Agency.

The report states the IRA no longer has the capacity to mount a military campaign anymore or return to one. The units that have been shut down were responsible for weapons-making, arms smuggling and training. The IRA decommissioned their arms last year.

The report also mentions that the IRA has also put its criminality beyond use and is “clamping down” on criminals within the organization, said Lord Alderdice, as he presented the report. He also added, “That doesn’t mean that criminal activity by all members has stopped but the leadership has made public statements and internal directions, investigated incidents of breach of the policy, even expelled some members and has emphasised the importance of ensuring that business affairs are conducted in a legitimate way.”

Finally, the report added that there is not enough evidence or intelligence to identify who killed Denis Donaldson, a British spy who infiltrated the IRA and Sinn Fein, before revealing his status as a spy.

However, the report added that splinter groups like the Real IRA (RIRA) and Continuity IRA (CIRA) are still threats and are still continuing their activity. The Real IRA was the group behind the deadly 1998 Omagh bombing. The Irish National Liberation Army (INLA) “was not capable of undertaking a sustained campaign [against the British State], nor does it aspire to” according to the report.

It is also noted the creation of two new organizations, Oglaigh na hEireann (Irish Gaelic for “Volunteers of Ireland” and is used by the Irish Defence Forces and the various IRAs.) and the Republican Defence Army. However, the groups are small dissident factions according to the report.

The report also added that the two loyalist paramilitaries, the Ulster Defence Association (UDA) and the Ulster Volunteer Force (UVF) are also beginning to move from violence but at slower pace and not at a grassroots level like the IRA. Another loyalist paramilitary, the Loyalist Volunteer Force

The report was received warmly by Irish Toaiseach Bertie Ahern and British Prime Minister Tony Blair. Ahern, said “These positive and clear-cut findings are of the utmost importance and significance. It is time to make decisions and for Northern Ireland to look to the future.”

“The IRA has done what we asked it to do, and while issues like policing remain to be solved, the door is now open to a final settlement, which is why the talks next week in Scotland are going to be so important.” said Tony Blair in a live statement.

In a surprising reaction, the notoriously hardline leader of the Democratic Unionist Party, Ian Paisley, also welcomed the report. He believes that his party’s pressure is working and if Sinn Fein signs up to policing there could be a deal. Paisley said, “If the police question is settled absolutely on a democratic basis and principle we would have come a long way along the road.”

Sinn Fein leader Gerry Adams said “The DUP don’t have anything other than very limited options. They will or will not participate in power-sharing arrangements. If they don’t participate they are condemning people here, but particularly their own constituents, to second class public services, run by second class fly-in, fly-out British ministers. All the DUP can do is to delay, is to attempt to slow down, but they can’t stop the process of changing.”
