The area's MP Brendan O'Hara is hosting a reception detailing plans for the former Nato base at Machrihanish to be the centre of space tourism in the UK.
Machrihanish is among five sites across Britain - three of which are in Scotland - hoping to be a spaceport.
The UK government has previously said it wanted to establish a spaceport by the end of 2018.
It launched a consultation in 2014 and two years ago it drew up a shortlist of potential sites.
These also included Prestwick in South Ayrshire, Stornoway in the Western Isles, Newquay airport in Cornwall and Llanbedr airport in the Snowdonia National Park.
In May last year, the government included plans for spaceport licensing in its Queen's Speech.
It also opened up the competition in favour of an airport-style licensing system, meaning any suitable location could become a spaceport.
The Department for Transport said this would help create "viable business models at a range of locations".
This meant that Prestwick and Campbeltown are both vying to attract investment to prove they are "best-placed" to become the UK's first operational spaceport.
Ministers said any future spaceport would be used as a base for space travel and tourism, as well as satellite launches.
The Machrihanish base, near Campbeltown, has twice been approved for space flight and was a certified emergency landing site in Europe ahead of a launch of the NASA Space Shuttle in 1981.
Tom Millar, chairman of DiscoverSpace UK and the Machrihanish Airbase Community Company, said the local community was behind the bid and the potential economic benefits it could bring.
He added: "Our site offers enormous scope with a runway of more than 3,000 metres and large areas of land available for development, allied to a positive and supportive planning framework put in place by Argyll and Bute Council.
"Our safety case is very strong as the site is in a depopulated area and offers the ability to launch directly over the sea."
Brendan O'Hara, the SNP MP for Argyll and Bute, said basing the spaceport in Kintyre was a "no-brainer".
He added: "A spaceport would bring important economic benefits to Argyll and Bute and it is a hugely exciting prospect for Scotland to be at the forefront of space travel in the UK. The sky is not the limit."

The Lancastria troopship was carrying between 6,000 and 9,000 people when it was sunk by German dive bombers on 17 June 1940.
Only about 2,500 people survived in the largest single loss of life for British forces in the whole of World War II.
Relatives and survivors have until 15 May to apply for a commemorative medal.
The Scottish government commissioned a medal in 2008, issuing more than 375 since.
The upcoming 75th anniversary of the event signals the closure of the commemorative medal application process.
The Lancastria, a converted Cunard liner built on the Clyde, was carrying servicemen - including about 400 Scots - and a number of civilian women and children when it was bombed by German planes, sinking within minutes off the coast of France.
At the time news of the disaster was suppressed by the British government because of the impact it might have on the country's morale.
Nearly six weeks later the New York Times broke the story, printing dramatic pictures of the disaster.
Veterans' Secretary Keith Brown said: "We in Scotland feel a strong bond with the servicemen and women who have served us throughout the years and continue to protect the democratic freedoms we still enjoy today.
"The commemorative HMS Lancastria medal from the Scottish government is a lasting reminder of our gratitude to those who made the ultimate sacrifice on that fateful day. Their memory is honoured, their place in history is secured."
Mr Brown appealed for anyone who believes they or a family member is entitled to a medal to come forward and make a claim.
Plans for the UK's first spaceport on the Kintyre peninsula are being unveiled at Westminster.
